As for file management, that's one area where Apple had it right and then buggered it up. Everyone agrees that spatial Finder was a revolution in working with files visually, then Apple changed to navigational Finder for OS X. Boo.
I'd love to hold a contest where we test people's productivity on each platform because whenever I watch someone who "likes it better than anything else" and supposedly knows even how to use a Mac, they're obviously incompetent when you watch them try to use it. It's absolutely hilarious watching someone trying to quickly find the application window that they want to switch to on a Mac, especially if they've full-screened some windows. (You aren't even allowed to have a real maximize function that always works the way you expect it to in every application lmao!)
